Credit: Mark Batke / Photo editorUrban Meyer’s call might have been answered this spring after the Ohio State coach spent most of the 2014 season preaching the need for depth at defensive line.Despite losing starters Michael Bennett and Steve Miller to graduation, OSU defensive line coach Larry Johnson said redshirt-sophomore Tyquan Lewis, sophomore Jalyn Holmes and redshirt-freshman Sam Hubbard have stood out through the first 10 practices this spring.“Tyquan is having a great spring, really great spring,” Johnson said Thursday. “Jalyn is starting to be the player we think he can be. Sam’s kinda out of nowhere, but really got a chance to be really dynamic also.”Lewis and Holmes combined for a total of 20 tackles last season, with Hubbard sitting out as a redshirt. Holmes totaled 11 tackles, one for loss, and Lewis added nine tackles with half a sack.Of the three, Johnson said Lewis has made the biggest strides since OSU’s victory in the College Football Playoff National Championship in January.“It’s clicked in his mind, the kind of player he has to be,” Johnson said. “He’s playing much faster than he played last year. And I think he understands the defensive concept much more than he did last year. But he’s had a really outstanding spring.”While Lewis played in 13 of the Buckeyes’ 15 games last season, he never cracked the regular rotation. Now with the goal of defending its national title, OSU is looking to replace the production of Bennett and Miller, who combined for 75 total tackles and eight sacks as seniors.The Buckeyes’ most productive defensive lineman, junior Joey Bosa, is set to return after totaling 55 tackles, 21 tackles for loss and 13.5 sacks on his way to being named a unanimous All-American. Bosa acknowledged that there wasn’t much depth on the line last year, but added the confidence he has in his backups has changed this spring.“Last year, we didn’t feel too comfortable with putting some backups in,” Bosa said Thursday. “But this year is a completely different feeling, we have a bunch of guys ready to go.”Like his coach, Bosa said Lewis has been the standout player of the bunch. He said Lewis has earned the starting spot opposite himself at defensive end, and added that he’s done “an unbelievable job” in practice.“He’s out there killing it, going hard every day,” Bosa said. “We’re all so happily surprised to see him do that, and I’m excited to have another end doing that.”Bosa said Lewis has speed and physicality, calling him a “freak” on the field.But while one player has stood out, Bosa added that Holmes and Hubbard have come out strong as well.“Jalyn Holmes and Sam Hubbard, my little protégés,” Bosa said. “They’re doing great, too. They’re out there working, Sam’s gotten so unbelievably better.”Overall, Johnson said he likes where OSU’s defensive line is going as spring practice winds down.The Buckeyes are scheduled to take the field for their annual Spring Game on April 18 before taking on Virginia Tech on Sept. 7 in Blacksburg, Va., to open the regular season. read more

Mourinho tease Juve fans after recent loss

first_imgJose Mourinho has taken a swipe at Juventus fans by challenging them to match his treble feat at Inter Milan following their loss at Old Trafford.Mourinho’s men were undone by a solitary strike from Paulo Dybala which was truly deserved considering their dominance in the game.However, the Portuguese manager believes the outcome of the tie would have been different if they had more options off the bench.“I think with the way we ended the game for the last 20 minutes, it would’ve been very different if we had Marouane Fellaini or Alexis Sanchez to take off the bench,” Mourinho told Football Italia.Jose Mourinho, Lionel MessiMourinho: “Lionel Messi made me a better coach” Andrew Smyth – September 14, 2019 Jose Mourinho believes the experience of going up against Barcelona superstar Lionel Messi at Real Madrid made him a greater coach.“We had a super-difficult game just two days ago. In any case, Juve have a great deal of quality. We did what we possibly could with heart and in my opinion a positive approach.“We knew when the draw was made that we’d be fighting Valencia for second place in the group.”Tensions flared up in the final minutes, as some of the travelling Juve fans insulted Mourinho, and he responded by holding up three fingers to represent Inter’s 2010 Treble – something Juventus have never achieved.“It’s an obvious response. Obviously, they don’t love me. Obviously, the toughest moment for them was our Treble. That’s fine. With players, Coaches, club and everything, we have total respect, everything is very cordial.”last_img read more

Astronomers discover two new inflated hot Jupiters

The content is provided for information purposes only. © 2016 Phys.org (Phys.org)—An international team of astronomers led by Joel Hartman of Princeton University has detected two new “hot Jupiter” exoplanets, less massive than our solar system’s biggest planet, but with a radius larger than they should have. The findings are reported in a paper published Sept. 9 on arXiv.org. Explore further The newly found exoworlds, designated HAT-P-65b and HAT-P-66b, were classified as “hot Jupiters” as they are gas giant planets similar in characteristics to Jupiter, with orbital periods of less than 10 days. They have high surface temperatures as they orbit their host stars very closely. However, the new alien worlds are much larger in diameter than expected, which led astronomers to conclude that these planets must have undergone an inflation process.HAT-P-65b and HAT-P-66b were detected by the Hungarian-made Automated Telescope Network (HATNet). The team also conducted follow-up spectrographic and photometric observations to determine physical characteristics of these planets.According to the research, the exoplanets orbit two distant, moderately evolved stars named HAT-P-65 and HAT-P-66 that are approaching the end of their main sequence lifetimes. HAT-P-65 is 5.46 billion years old, while HAT-P-66’s estimated age is 4.66 billion years. They are located some 2,750 and 3,000 light years away respectively. Both stars are similar in size, having radii of about 1.87 solar radii and mass of approximately 1.25 solar masses.The newly discovered planets are less massive than Jupiter—HAT-P-65b has only half the mass of Jupiter, while HAT-P-66b about 78 percent the mass of our gas giant. The orbital period of this two worlds equals 2.60 and 2.97 days correspondingly.What is the most intriguing about these two extrasolar planets is that they are larger than they should be when compared to typical gas giants. HAT-P-65b has a radius of nearly 1.9 Jupiter radii and HAT-P-66b is about 1.6 the size of Jupiter in diameter. This suggests that the two exoplanets are inflated gas giants.However, further investigations and new detections are still needed to determine precisely what causes the inflation process in gas giant planets. Currently, possible explanations could be assigned to two different theories—scientists believe that the inflation is caused by deposition of energy from the host star or inhibited cooling of the planet.”One way to make further progress on this problem is to build up a larger sample of inflated planets to identify patterns in their properties that may be used to discriminate between different theories,” the researcher wrote in the paper.The discovery of HAT-P-65b and HAT-P-66b, complemented by previous studies reporting the detection of inflated planets, allowed the team to find an important correlation between planetary radii and the fractional ages of parent stars, which makes the theory regarding the deposition of energy more plausible.”The planets are both around moderately evolved stars, which we find to be a general trend—highly inflated planets with a radius larger than about 1.5 Jupiter radii have been preferentially found around moderately evolved stars compared to smaller-radius planets. (…) We conclude that, after contracting during the pre-main-sequence, close-in giant planets are re-inflated over time as their host stars evolve. This provides evidence that the mechanism responsible for this inflation deposits energy deep within the planetary interiors,” the paper reads. More information: HAT-P-65b and HAT-P-66b: Two Transiting Inflated Hot Jupiters and Observational Evidence for the Re-Inflation of Close-In Giant Planets, arXiv:1609.02767 [astro-ph.EP] arxiv.org/abs/1609.02767AbstractWe present the discovery of the transiting exoplanets HAT-P-65b and HAT-P-66b, with orbital periods of 2.6055 d and 2.9721 d, masses of 0.527±0.083 MJ and 0.783±0.057 MJ and inflated radii of 1.89±0.13 RJ and 1.59+0.16−0.10 RJ, respectively. They orbit moderately bright (V=13.145±0.029, and V=12.993±0.052) stars of mass 1.212±0.050 M⊙ and 1.255+0.107−0.054 M⊙. The stars are at the main sequence turnoff. While it is well known that the radii of close-in giant planets are correlated with their equilibrium temperatures, whether or not the radii of planets increase in time as their hosts evolve and become more luminous is an open question. Looking at the broader sample of well-characterized close-in transiting giant planets, we find that there is a statistically significant correlation between planetary radii and the fractional ages of their host stars, with a false alarm probability of only 0.0041%. We find that the correlation between the radii of planets and the fractional ages of their hosts is fully explained by the known correlation between planetary radii and their present day equilibrium temperatures, however if the zero-age main sequence equilibrium temperature is used in place of the present day equilibrium temperature then a correlation with age must also be included to explain the planetary radii. This suggests that, after contracting during the pre-main-sequence, close-in giant planets are re-inflated over time due to the increasing level of irradiation received from their host stars. Prior theoretical work indicates that such a dynamic response to irradiation requires a significant fraction of the incident energy to be deposited deep within the planetary interiors.
